Circlip Installation

Justin from MAHLE Motorsports goes over different methods of installing round wire locks, or circlips, on your pistons.

[@Anonymous-it5jw]

The tip for using the binder clip a a temporary wrist pin retainer is genius. Your shop-made tang install tool that twists the ring in place is also a great idea.

[@william-billy-woodall1271]

Thank you for this video and for showing the tanged clip position picture with the slanted edge. Life saver. You’d think the company would include instructions…keep up the great work!

Best video I've seen yet on wire lock installation.

[@Sketch1994]

5:34 the piston I run have a relief on one side but have the removal notch on it...on the other side the ring slides directly onto the piston skirt! In a complete teardown and rebuild the most dreaded thing is getting the second clip on while the piston is on the connecting rod! Also installing those clips by hand usually gets a piece of your skin in the groove as well! I' m definitely making some of these clip tools you showed here!

Thanks for this video, this is the most informative one I've found so far. I tried for over an hour to install the first circlip last night, and had to just stop before I rage smashed something on my workbench, or damaged my piston. Every other video I've found just basically says "oh you just pop it in" and show little to no effort. Your example is much more like what I'm up against installing clips in a new piston for my KLR650.

[@millerzion6863]

@Marcus Tristan I really appreciate your reply. I got to the site on google and im waiting for the hacking stuff now. Seems to take a while so I will get back to you later when my account password hopefully is recovered.

[@millerzion6863]

@Marcus Tristan it worked and I now got access to my account again. Im so happy:D Thanks so much, you really help me out :D

[@marcustristan208]

@Miller Zion No problem :D

[@stevebennett6593]

cool... i just went out and made on of these on my lathe... nearly cried it was so successful.

[@nightcatbooks]

lol I watched this video to fix a circlip on my lathe!

[@kernahanbuck6507]

Excellent presentation.

[@amathonn]

I was struggling to get a c clip retainer back in place near the end of a rod that supports my mower deck when i watched your video. I have a tool designed for that --but it was 67 miles away. Luckily the rod end by the clip groove was beveled and i had a box end wrench a smidgen bigger than the rod and about the same size as the clip. Pressed it on first try.

[@jacks19822]

thanks so much this really helps.

[@TheOnlyRedNeckGeek]

Thank you SO MUCH for posting this video. Been struggling with the "W" company's really stiff wire circlips for years, and made your straight aluminum tool. Took a while to get the dimensions right, but when I did, it worked like a charm. Can you provide any guidance as to the proper dimensions for the business end of that tool (shown at 4:36)?

[@WebelOne]

Thanks for the content super helpful!

[@Tips_Hacker]

Nice video

[@mortirius1]

I like to use a little aluminum sheet metal to put where the scratch happened to prevent the scratch it also helps slide it in

[@bernardthefourth]

Pro tip, I tape a beer bottle cap to my lower thumb to push it on. On my Porsche you have to install the pistons onto the rods while the liner is hovering above them with the rings in the liners. It's a real bitch!

[@marklowe7431]

Genius

[@WhiteblurrST]

Where do you get the 23mm clip tools?

[@Daemione]

Would love to see how this is done on a Subaru engine... i.e. a couple inches into the block, no access for more than a single tool, and no hands. :)

[@edwing60]

where can i buy this tools??

[@neamtialin]

Dig out notches should be mandatory everywhere there are circlips involved

[@munitwidodo5305]

Where to buy this tools???

[@sokkimtith8266]

Hello brother, how can i buy the tool

[@doobyboy21]

Hi I can't seem to find those tools on your website ?

[@mahlemotorsport]

+doobyboy21 Sorry for the late reply, but these can be found in our application guide. We have two different sizes of those tools that we sell, one for .927" and another for .990". These part numbers are W-927 and W-990. Again, sorry for the late reply, let us know if we can be of any more help.

[@abdelkaderdricitani3809]

And what happens if we forgot to put circlips

[@rickh9306]

Okay, so I watched this video and learned a few things. However I would like to know where I can get one of the aluminum circlip installation tools. I am not interested in the plastic or nylon version. The aluminum tools seem to work quite well at least in the video. Thank you. Rick H.

[@olenaerhardt7725]

I removed Cv Axle and saw that the Circlip on the CV Drive Shaft is kind of loose. You can rotate it easily inside of its grove easily. I plan to replace it. The original clip is made fm/white metal, looks like Stainless Steel. On Amazon I didn't see any Stainless Steel circlips and bought cirlips fm/Carbon Spring Steel. Is it better to put that Carbon Steel circlip instead of loose Stainless Steel one? How tight should be that ring in the grove? Thank you for the great film.

[@mahlemotorsport]

Thank you. CV Axles are a different application. Best to consult with the manufacturer of the CV Axle.

Unfortunately we do not have the capability to make a piston that small in diameter in the Motorsport division.
